Answer: $371.39
Explanation:
The formula to calculate the compound amount after t years is given by :-
, where P is the principle amount and r is the rate of interest.
Given: Principle amount =$150
The rate of interest = 12%=0.12
Now, the amount compounded after 8 years will be:-

Hence, the value of $150 after eight years if you earn 12 percent interest per year would be $371.39.
